Practical Obstetrics and Gynaecology, Second Edition is an essential undergraduate textbook in obstetrics and gynaecology for Hong Kong medical students. It provides a comprehensive overview of all the topics in the core curriculum of obstetrics and gynaecology. In addition to the description of various diseases, there is also discussion on the evidence-based approach to the differential diagnosis and management of common symptoms/presentations in obstetrics and gynaecology. Where appropriate, flow charts and diagrams are used to help readers to make a diagnosis. The book also includes updated information on diseases that are more common in Asia. While this book is mainly written for medical students, it is also a useful basic reference for student midwives, practising doctors, and other healthcare professionals who are involved in women’s healthcare.

Simply keeping the mind clear and calm was, for many post-Tang Daoists, the path to eternal life and freedom. Through sheer serenity, practitioners believed they could attain immunity to hunger, eliminate sexual function, suspend breath and pulse, engage in astral travel, and command spirits and natural forces.In his meticulously researched study, Stephen Eskildsen examines how this perspective informed Daoist internal alchemists after the Tang dynasty (618–907), including prominent representatives of the Quanzhen tradition in the north and the Nanzong in the south. Drawing on a wide array of textual sources, he analyzes the teachings of figures like Qiu Chuji (1143–1227), Yin Zhiping (1169–1251), Zhang Boduan (ca. 984–1082), Bai Yuchan (1194– 1229), Li Daochun (fl. 1288–1292), Yu Yan (ca. 1253–1314), and Wu Shouyang (1574–after 1641), among others. These adepts emphasized passive, straightforward methods that they believed gave rise to spontaneous psychic, sensory, and physiological p

In 2018, authorities in Hong Kong seized a shipment from smugglers that contained 88 dead pangolins. Where did these animals come from, and why were they killed? Where were they going? Who was responsible? In classic true crime fashion, the book examines evidence, suspects, and legal perspectives related to this specific case and, through it, the plight of pangolins globally. The chapters detail the lives and natural history of pangolins across Africa and Asia while exploring clues that may reveal who is responsible for the endangerment of the species. The book also explores speculation surrounding the possible role of pangolins in the emergence of COVID-19 and, more broadly, the relationship between wildlife trade and zoonotic disease. The resulting tale is one of conservation researchers, public health experts, and global organizations across Asia, Africa, North America, and Europe fighting to create a world in which pangolins can thrive again.

Tracing the global echoes of China sounds, mapping a new auditory history of migration, diaspora, and modernity.Tracing the global journeys of Chinese sounds from the nineteenth century to the present, this volume charts a vast sonic territory: from Cantonese opera arias in San Francisco to the “Far East sound” that shaped Jamaican reggae, and from the melodies of pigeon whistles over Germany to the revolutionary anthems of Cold War Italy… How have these sounds—traveling via migration, media, and diplomacy—been heard, adapted, or even rejected in disparate cultural landscapes?Through seventeen case studies spanning Asia, the Americas, and Europe, the book uncovers the myriad ways sounds interpreted as “Chinese” are transformed, contested, and imbued with new meanings as they reverberate across geopolitical and cultural borders. This collection provides a novel auditory history of China’s global entanglements, offering a comparative lens to understand the dynamic role of sound in transn

Zhao Hai Tien’s creative explorations are characterized by the diversity of media in her work—from airbrush on glass and acrylic on canvas to calligraphic experiments, large-scale public murals and oil paintings. Her practice blends technical precision with expressive freedom and spiritual influences. Over more than three decades of Buddhist and Taoist study—and twenty-four years under the guidance of a respected qigong master—Hai Tien’s work has shifted from contemplative, figurative compositions to liberated, spiritually resonant expressions that capture the flow of energy and inner awareness in vibrant, form-defying strokes.Her first solo show, Recent Works of Hai Tien, opened at the Alliance Française in Hong Kong (1972), launching a sustained presence in the local art scene, and leading to solo exhibitions in Hong Kong, Shanghai, and Berlin. Her work was also presented in prestigious group exhibitions across Asia, including the First Hong Kong Biennale (1971). Her most notable pub

In the early twentieth century, oil painting as a non-indigenous medium began to be taught in Chinese art academies. Since that time, it has become an important and increasingly popular portal, inviting artists to explore cross-cultural dynamics and experiment with individual creative expression.This selection of twentieth-century Chinese oil paintings from the UMAG collection sheds light on the art historical and cultural significance of the medium. Highlighting the versatile aspects of Chinese oil paintings across a diverse spectrum of themes, styles, techniques, time periods, and regional and local characteristics, this publication presents the depth and virtuosity of Chinese oil paintings, extending from intimate interior views to panoramic coastal landscapes. The collective and individual memories within urban scenes activate dialogues of painting practices across time, space, and cross-cultural and cross-media encounters.The selected works display and represent the various artist

The rulers of the Ming dynasty enacted paradigms of hierarchical order. Like imperial families, households, and courts in earlier Chinese dynasties, they articulated patriarchal, patrilineal, and patrilocal organizational principles as exemplars for families and institutions throughout the empire. Women made indispensable contributions to the development of these paradigms and principles and to the social, cultural, and political fabric of the family and the state. And yet, in the existing literature in Chinese and English women are often burdened with stereotypes, positioned as peripheral, or rendered almost invisible.Reading available texts “against the grain,” and drawing on a trove of evidence from material culture, Soulliere shows how women defined a place for themselves in the multigenerational Ming imperial family, imperial household, and court. The Empress and the Dragon Throne spans the first Ming century from just before the founding of the dynasty in 1368 to the end of the T

Although the arts have been firmly planted in the Hong Kong school system since the 1950s, they are often sacrificed in place of core subjects and preparation for examinations. Drawing on over fourteen years of exploration and experience, Yau makes the case that arts are critical to cultivating creative mindsets, which are our best resource for innovating and responding to challenges in this complex world of sudden changes. Through case studies and conversations with practising artists and educators, this book demonstrates why arts and education, two normally discrete disciplines, should be broadly integrated into the local Hong Kong curriculum, and how this can be – and has been – achieved.This book is intended for policymakers, educators, arts heads, and artists. The volume will also appeal to readers curious about how and why the arts should be foundational to education and capacity building in the twenty-first century.

This year (2025), on the 50th anniversary of my public service starting as an Administrative Officer in the Hong Kong Government and morphing into a politician, after many twists and turns, I am pleased to publish the ninth edition of my series of books entitled “Regina’s English Works for You”.The articles collected in this year’s “Regina’s English Works for You 9” fall under three broad areas: “Hong Kong’s Recovery and Resurgence” after our re-opening in early 2023, “Opportunities in the Greater Bay Area”, and “Emerging Rivalry between the East and the West”. The articles are a reflection of the global trends reshaping the world and life in Hong Kong. I hope readers can glean from these pieces some insight about the way the world is heading, and how we should position ourselves in a world transformed by “changes unseen in a hundred years”.I hope you will enjoy reading these fairly short and readable pieces and, in the process, learn one or two new things about mastering the English

A world-leading expert on Myanmar assesses the ongoing popular uprising against the military junta that deposed Aung San Suu Kyi.Myanmar’s generals didn’t expect the nation to rise up against the coup they staged in February 2021. But after decades of stifling, direct military rule, the Burmese people had become used to another way of life during the relative openness of 2011–21. The army has been unable to suppress anti-coup protests as it did in 1962 and 1988; and, three years after sending tanks into Yangon, Naypyitaw and other cities, the army has yet to establish a functioning administration.For the first time since the 1970s, armed resistance is not confined to traditionally strife-torn frontier areas, where ethnic insurgents like the Karen National Union and Kachin Independence Army have been active for decades—it has spread to the majority-Burmese heartland, in the shape of the People’s Defence Forces. But the anti-junta forces are insufficiently well-equipped to defeat the muc

A compilation of Ting Yin Yung's paintings and other artwork from his life in Hong Kong. University Museum and Art Gallery's exhibition is authoritative in its display of Ting Yin Yung's oil and ink paintings, watercolors, sketches, and seals, all of which cover the most productive decades of his working life in Hong Kong. The project is also highly community-centered, as the development of this project benefited greatly from the input of Ting's students, who continue to treasure their master's passion and the instructive lessons and conversations that nurtured a generation of local artists. A native of Maoming County in Guangdong province, Ting Yin Yung first studied Western painting in Tokyo at the Kawabata Painting School in 1920, and then at the Tokyo School of Fine Arts. He began working in mainland China in 1925, before emigrating to Hong Kong in 1949, where he developed his artistic practice as a painter, seal carver, and greatly admired teacher. Heavily illustrated in full colo

In Redefining Heresy and Tolerance, Hung Tak Wai examines how the Qing empire governed Muslims and Christians under its rule with a non-interventionist policy. Manchu emperors adopted a tolerant attitude towards Islam and Christianity as long as political stability and loyalty remained unthreatened. However, Hung argues that such tolerance had its limitations. Since the mid-eighteenth century, the Qing court intentionally minimised the importance of the Islamic identity. Restrictions were imposed on the Muslims’ external connections with Western Asia. The Christian minority was kept distant from politics and the Han majority. At the same time, Confucian scholars began to acquire a new understanding of religion, but they were not encouraged to get in touch with the Muslims and Christians. This book demonstrates how, from the late eighteenth to the early nineteenth century, the Qing government prevented Confucian scholar-bureaucrats from interfering in the religious life of Christians an

In the third edition of Contemporary Hong Kong Government and Politics, Lam Wai-man, Percy Luen-tim Lui, Wilson Wong, and various contributors provide the latest analyses in many aspects of Hong Kong’s government and politics, such as political institutions, mediating institutions, and political actors. They also discuss specific policy areas such as political parties and elections, civil society, political identity and political culture, the mass media, and public opinions after the Umbrella Movement in 2014. The book also evaluates the latest developments in Hong Kong’s relationship with Mainland China and the international community. This new edition offers an up-to-date and comprehensive analysis of the main continuities and changes in the above aspects since 2014. This volume will help its readers grasp a basic understanding of Hong Kong’s political developments in the last ten years.

An exploration of collective memory through the lens of East Asian film during World War II. Taking the "tidal wave" of memory in the late twentieth and early twenty-first century as its starting point, this monograph explores the collective memory of World War II in East Asia (1937-1945) through film. Weiss argues that Chinese, Japanese, and American remembrance of World War II is intertwined in what she terms a "memory loop," the transnational mediation and remediation of war narratives. Gender is central to this process, as the changing representation of male soldiers, political leaders, and patriarchal father figures within these narratives reveals Japanese and Chinese challenges to each other and to the perceived "foundational" American narrative of the war. This process continues to intensify due to the globally visible nature of the memory loop, which drives this cycle of transmission, translation, and reassessment. This volume is the first to bring together a collection of Chin

New research on the history of public housing and squatting in Hong Kong. In Hong Kong Public and Squatter Housing, Alan Smart and Fung Chi Keung Charles trace the development of squatting in Hong Kong from 1963 to 1985. The authors reconstruct government policy on squatting through both ethnographic and archival research. This book sheds new light on the consequences of various attempts to control encroachment on scarce urban space. The authors argue that intersecting policy agendas resulted in decisions that were often not desired, but which emerged as practical solutions from prior failures. They address the challenges of explaining confidential policy decisions and offer new approaches applicable in other contexts. Overall, this book makes an important contribution to the understanding of how public housing and squatting interacted in influential ways that have been poorly understood and offer new perspectives on the challenges of urban governance and housing problems.

How do we situate ourselves when we navigate the city of Hong Kong—physically, and in our minds? Against a backdrop of bustling density and movement, the difficulties of making space have shaped our days. From the challenges of limited living space and the quest for personal space, to the everyday negotiations of our identities in the social space, we are constantly confronted with the question: How do we redefine the distance between the city, others, and ourselves, and between the selves within us? This collection features prose, poetry and artwork from writers and artists in or from Hong Kong, as well as those who have had a close connection with the city, that explore the (im)possibility of making space. How do we remake space in our lives and our creative practices? What does this (im)possibility mean in (or in relation to) Hong Kong today?

A pioneering and comprehensive study of recent Malaysian cinema. Malaysian Cinema in the New Millennium offers a new approach to the study of multiculturalism in cinema by analyzing how a new wave of filmmakers champion cultural diversity using cosmopolitan themes. Adrian Lee offers a new inquiry of Malaysian cinema that examines how the "Malaysian Digital Indies" have in recent years repositioned Malaysian cinema within the global arena. The book shines a new light on how politics and socioeconomics have influenced new forms and genres of the post-2000s generation of filmmakers and provides a clear picture of the interactions between commercial cinema and politics and socioeconomics in the first two decades of the new millennium. It also illustrates how the Malaysian Digital Indies functions as a site for questioning and proposing a new national identity in the era of advanced global capitalism and new Islamisation.

In Daily Giving Service: A History of the Diocesan Girls’ School, Hong Kong, Moira M. W. Chan-Yeung and her fellow contributors present a comprehensive history of one of Hong Kong’s oldest girls’ schools. As an alumna of the school, Chan-Yeung traces the history of her alma mater from its establishment in 1860, to its development over the last 160 years until the recent decade. Having experienced stability and turbulences in Hong Kong in the twentieth century, the school has become one of the most prominent girls’ schools in the city. In several chapters written by other alumnae, various aspects of school life of different eras are reconstructed and remembered.The author and other contributors focused on the postwar era in which Hong Kong grew from a small city to a global metropolitan. The expansion of the Diocesan Girls’ School largely followed this trend. The history of the school has also long been connected with the socio-economic development of Hong Kong society, sharing its happ

Psychopathology: An Empathic Representational Approach retraces the foundations of classical phenomenological psychopathology and integrates them with modern ideas drawn from anthropology, cognitive neuroscience, computational science, and evolutionary biology to synthesize a comprehensive framework and provide fresh insights.This book explores how the scientific concepts of ‘information and representation’ can be used to understand subjective mental phenomena and integrate them in empathic clinical dialogues during interactions with patients. It explores key issues in clinical psychopathology coherently and systematically, illustrates advanced topics in an accessible manner using clinical case examples, metaphors and clarifying diagrams, and directly links advanced conceptual frameworks with pragmatic skills in the clinical dialogue process.This volume is aimed at a broad audience of mental health professionals, researchers, and students in psychiatry, psychology, and social work.

This book, Chiang Yee and His Circle: Chinese Artistic and Intellectual Life in Britain, 1930–1950, celebrates the life and work of Chiang Yee (1903–1977), a Chinese writer, poet, and painter who made his home in London, England during the 1930s and 1940s. It examines Chiang’s relationship with his circle of friends and colleagues in the English capital, and assesses the work he produced during his sojourn there. This edited volume, with contributions from eleven distinguished scholars, tells a story of a Chinese intellectual community in London that up to now has been largely overlooked. It portrays a dynamic picture of the London-based émigré life during the years that led up to the war and during the conflict that was the catalyst for many of them moving on. In addition, the book broadens our understanding of cultural interactions between China and the West in Hampstead, one of the most vibrant artistic communities in London.

Set against the backdrop of regional and international post–Second World War tensions, Grounded at Kai Tak is the most comprehensive account of the complex legal struggle for ownership of 71 airplanes belonging to the two main Chinese airlines, which were stranded at Kai Tak airfield in Hong Kong at the end of the Chinese civil war. The resulting contest for possession of them took place in the courts and among politicians and diplomats on three continents. In the process, the struggle became entangled with the anti-communist policies of the United States in the emerging ‘Cold War’, British hopes for restoration of her pre-war commercial position in China, disagreements between nations about recognition of the new government in Peking, and the delicate balance that the colonial government of Hong Kong had to keep to preserve that colony’s interests.Merry tells the tale of this legal saga by weaving together archival documents and news reports of the day, revealing the international ali

Sir Robert Ho Tung (1862–1954) is a compelling figure in Hong Kong history. He is regularly portrayed as the colony’s greatest philanthropist and wealthiest man of his day, the first Chinese to live on the Peak, and, at the end of his life, the ‘Grand Old Man of Hongkong’. The illegitimate son of a Chinese mother and European father, he was highly sensitive about his mixed heritage though he consistently made the most of his fate. He was a man perfectly in tune with his place and time, his success driven as much by his entrepreneurial talents as by his being Eurasian. This book shows him in all his immense variety―clerk with the Imperial Maritime Customs, chief compradore of Jardine Matheson, financial wizard, husband and lover, patriarch of a large family of five sons and eight daughters, loyal British subject but also, paradoxically, Chinese patriot. China’s president Yuan Shikai awarded him the Order of the Excellent Crop, and King George V knighted him.May Holdsworth’s thoughtful a

Case studies from contemporary Asia on the intersection of nature and urban spaces. Two processes are currently unfolding in diverse patterns across contemporary Asian cities: the displacement of nature in urban spaces, as well as the reimagining of nature's place in the urban sphere. The rapid urbanization of Asia has provoked contentious debates and novel schemes about the role of nature in cities. Contributors to this volume gather case studies from across Asia to address projects of urban greening and other models for the integration of nature in urban life. The book also illustrates how the intersection of urban growth and urban nature is a sector rich with fresh ideas about urban planning, governance, and social life as debates and efforts to recover nature in the city provoke moral and ethical evaluations of the human ecology of city life.

In New Asian Disorder: Rivalries Embroiling the Pacific Century, Lowell Dittmer and his team explore the recent political disorder in East Asia resulting from growing Sino-American polarization. The rise of China in recent years is widely regarded as a momentous shift in the global balance of power. China is now extending sovereignty into the East China Sea and the South China Sea, constructing a new set of global financial institutions and replacing “universal values” with technologically enhanced nationalism. The country’s “Belt and Road Initiative” is also tainted by the vast ambition to realize the “China Dream” within the foreseeable future. In response to China’s challenge, the United States has abandoned its “constructive engagement” policy towards the rising power and engaged in a trade war. Sino-American relations have been at a historical trough since the normalization of their relationship in the late 1970s. This book sheds new light on the current political disorder in the

In Hong Kong’s Last English Bishop, Philip L. Wickeri explores the life and times of John Gilbert Hindley Baker, who served as Bishop of the Anglican Diocese of Hong Kong and Macao from 1966 to 1981. Baker lived through exciting times, as a missionary in wartime and revolutionary China, as a priest in America during the early years of the Cold War, and as a mission leader in the Church of England when churches in many parts of the world were becoming independent, before returning to Hong Kong where he was elected bishop. He was a faithful correspondent and a prolific writer throughout his life, offering a personal commentary on the churches and the societies in which he lived. Wickeri has made extensive use of Baker’s writings and other archival materials to provide a vivid picture of his life and work. Bishop Baker was instrumental in working for reconciliation after the 1967 riots, expanding the work of the diocese, and engaging Hong Kong with the wider world. In 1971, he opened a ne

Ikat Textiles of the Indonesian Archipelago offers a comprehensive overview of the profusion of ikat styles found across Indonesia, and is the first detailed reference book on the subject. Assessing Peter ten Hoopen’s Pusaka Collection from a scholarly point of view, it is worth acknowledging how it illustrates the concept of ‘unity in diversity’, which the young state of Indonesia chose as its motto upon independence. Here, the interwoven-ness of styles from neighbouring island regions matter, as do their marked individuality and idiosyncrasies. Moreover, it allows for the study not just of the people’s finery, but of their everyday clothing. An ironic illustration of the effect of this collecting method comes from Ili Mandiri on Flores. As its dark red bridewealth sarongs have been prized and venerated by the local population, this is what most sophisticated collections have aimed to obtain. The simple but lovely indigo sarongs for everyday use have been almost entirely ignored by co
